There are many diver interested in the cave of Asia.
I added the area information of Asia and Australia.
I was added in Australia because there was a little information though it was cave diving for many years.
The cave diving agency of CDAA is in Australia.
Of course, Australia is near from Japan.

I am happy when someone tells me the cave of Asia and Australian information.
Of course, it is glad even at the Japanese cave information.
